Thanks for the reminder. I have put it on my staging branch for now.
Once rc3 gets tagged with irqchip related changes, I will move this
over to next.

Now, that said, Please consider converting
Documentation/devicetree/bindings/pci/pci-keystone.txt to yaml
sometime in near future, if possible.

We might also want to spend a little more time with W=2 dtbs build and
dtbs_check to cleanup.
